2 Claims.

This invention relates to a coin or check which is adapted to be used inslot machines, check testing apparatus and the like, and more especiallyto a check which is adapted for use with a mechaz. nism shown anddescribed in my co-pending patent application Serial No. 32,420, filedJuly 20, 1935, Patent No. 2,073,392 of March 9, 1937.

In many States of the Union there is an existing law which prohibits theuse of any check in a slot machine, game board, check testing apparatusand the like, which is of the same diameter -as a genuine coin.Therefore, it is necessary to substitute therefor a coin or check whichis of slightly less or slightly larger diameter than that {of a genuinecoin. Since the check testing apparatus shown in my said co-pendingpatent application has means for testing the surface configurations, thethickness, and the diameter of a coin before accepting the same, it isnecessary to provide a coin or check which will comply with the testsapplied to a coin or slug inserted therein by this apparatus.

As stated in my co-pending patent application, the feelers, which engagethe faces of the coin or check for testing the surface configuration are\equally spaced in a circular row so that the ends thereof will engagethe surface of the coin or check. If all of the feelers are actuatedexactly the same amount as a result of all the points of contact beingat the same level on the face of the coin, then the coin will berejected. In order for ,the coin to be tested as to its surfaceconfiguration, some of the feelers will have to be actuated more thanthe others as a result of the irregularities on the face of the coin. Inorder to insure that this effect will be produced on the feelers, thecoin or check has been designed so that certain feelers will be sure tohit a high spot on the surface of the coin and certain of the feelerswill be sure to engage a depression thereby actuating the feelers anunequal amount.

It is therefore, an object of this invention to 7 {provide a circularcheck for use in a check testing apparatus having a plurality of spaceddepressions therein arranged in a circle whose cen- .ter is the centerof the circular row of feelers which are adapted to be pressed againstsaid check, the feelers and the depressions being unlike in number toinsure that the feelers will be actuated unevenly to cause the check topass the *surface configuration test.

Some of the objects of the invention having been stated, other objectswill appear as the description proceeds when taken in connection withthe accompanying drawing, in which:-

Figure 1 is an isometric view showing one side of the invention;

Figure 2 is an isometric view showing the opposite side of the inventionfrom that shown in Figure 1; V

Figure 3 is a sectionalview taken along line .3-3 in Figure 2;

Figure 4 is an elevation of a check similar to that shown in Figures 1,2 and 3, but having the depressions on opposed sides thereof in astagered relation to each other; v

Figure5 is an elevation of a slightly different 'modified form of theinvention constructed along the same lines as that shown in Figure 4;

Figure 6 is a sectional view taken along line 6-43 in Figure 5.

Referring more specifically to the drawing, the numeral l0 denotes asuitable coin or check which is adapted to be used in a slot machine,check testing apparatus and the like, said coin having a plurality ofevenly spaced depressions I I on the face thereof and a plurality ofsimilarly arranged depressions I2 are disposed exactly opposite eachother on the faces of the coin, thereby providing ridges or high placesl3 and I4 between these cavities. These high places or ridges l3 and I4are substantially at the same elevation or level as the other surfacesof the coin. The feelers in my co-pending application, Serial No.32,420, are evenly numbered and evenly spaced, there being ten feelersconcentrically spaced. The coin I0 is placed in the apparatus with thecentral portion thereof placed in coinciding relation with the center ofthe circular row of feelers.

It will be noted that in the coin l0 there are nine evenly spacedconcentric cavities II and 'nine cavities 12. When the coin is placed intesting position in the apparatus and the testing means or feelers arethrown into operation, some of the feelers will be sure to contact thehigh places It or M and some will be sure to engage the cavities H orl2, since the depressions and feelers are equally spaced on the checktesting apparatus and coin respectively, but the number of feelers anddepressions being unlike.

Figure 4 shows a slightly modified form of the invention in which thecoin l5 has a plurality of evenly spaced depressions [6 in one facetherefaces of the coin l5. Since the surface configurations of only oneface of the coin are tested when the coin is inserted into the checktesting apparatus, it is evident that the relative position of thedepressions on opposed side of the coin to the depressions on the testedside, does not materially matter except from a manufacturer'sstandpoint. form the stamps or dies in such a manner so that the coin orcheck will be stamped with the depressions bearing a staggered relationto each other on opposed faces of the coins Figure 5 shows anotherslightly modified form in which a coin 20 has a plurality ofconcentrically spaced circular depressions 2| disposed in one facethereof and a plurality of circular spaced depressions 22 disposed inits other face. These depressions on the opposed sides of the face beara staggered relation to each other as is shown in Figure 4. Likewise, inthis form, the portion 23 of the coin which is disposed between thedepressions 2| or 22 is at the same level as the other surfaces of thecoin.

It is therefore, seen that I have provided a check or coin ofpredetermined thickness and diameter, said coin having a plurality ofradially disposed depressions in each face thereof with ridges or highspots between said depressions so that the coins may properly complywith surface configuration tests applied in any coin testing apparatushaving a plurality of radially disposed feelers for testing the surfaceconfigura- In many cases it is desirable to tions which feelers are ofuneven number from the number of depressions in the face of the cointested.

In the drawing and specification there has been set forth a preferredembodiment of the invention, and although generic terms are employed,they are used in a generic anddescriptive sense only, and not forpurposes of limitation, the scope of the invention being set forth inthe appended claims.

I claim:

1. A check for use in a check controlled apparatus wherein a pluralityof feelers are arranged in a circle for engaging one side of the checknear its periphery, said check having a plane surface on each sidethereof and each plane surface having a plurality of spaced depressionstherein arranged near the periphery of the check in a circle whosecenter is the center of the check, the spaced depressions on one side ofthe check being disposed in a different radial plane from thedepressions on the other side of the check.

2. A circular check for use in check controlled apparatus and having apair of opposed plane side surfaces each provided with a plurality ofequally spaced depressions arranged near the periphery of the check in acircle whose center is disposed at the center of the check, the spaceddepressions on one side of the check being disposed in a differentradial plane from the depressions on the other side of the check.
